Definitions
- compositions for treating a patient suffering from a respiratory disease associated with chronic inflammatory disease and method of making and using the composition
- the invention relates to a composition for the treatment of a patient suffering from a chronic respiratory disease associated with respiratory disease according to claim 1, a method for producing the composition according to claim 10 and the use of such a composition according to claim 12.
- Chronic inflammation is of increasing importance in medicine. Accordingly, it is important to find therapies for diseases such as respiratory diseases, which are associated with chronic inflammation.
- respiratory diseases are for example allergic immediate type reactions, asthma or chronic obstructive pulmonary diseases (COPD).
- COPD chronic obstructive pulmonary diseases
- Th 1 cell-specific transcription factor Tbet induces the specific development of Th 1 cells;
- GATA-3 induces the specific development of Th2 cells.
- the balance between Th1 and Th2 cells is thus shifted by the expression of GATA-3 or by the inhibition of Tbet in favor of Th2 cells.
- the inhibition of GATA-3 and the expression of Tbet cause an increasing Th1 cell level.
- DNAzymes represent a relatively new class of antisense molecules.
- sense molecules refers to molecules that are capable of specific and substantially complementary to bind single-stranded nucleic acids (usually mRNA).
- mRNA single-stranded nucleic acids
- a special feature of DNAzymes is that they also have a catalytic function in addition to this binding function. They are thus able to specifically cleave and thus degrade single-stranded target DNA or RNA (Sei et al., 2008). In this case, one also speaks of post-transcriptional inhibition, because the inhibition of gene expression takes place at the mRNA level, ie even before the translation of the mRNA into a protein can follow
- DNAzymes of the 10-23 model are used (Sontoro et al., 1997). Such DNAzymes have a catalytic domain of 15 nucleotides flanked by two substrate binding domains.
- the catalytic domain may in particular comprise the conserved sequence ggctagctacaacga (SEQ ID No. 154).
- the specified sequence ggctagctacaacga is merely a preferred embodiment.
- DNAzymes of the 10-23 modified catalytic domain model may have comparable biological activity.
- the length of the substrate binding domains is variable, whereby two corresponding substrate binding domains may differ from one another.
- the length of the Substrate binding domains between 6 and 14 nucleotides, with a length of 9 nucleotides being particularly preferred.
- Such DNAzymes have a specific sequence such as nnnnnnnnggctagctacaacgannnnnnnn.
- the substrate binding domains are completely complementary to the regions flanking the intended cleavage site of the target mRNA - however, to bind and cleave the target RNA, the DNAzyme need not necessarily be completely complementary.
- DNAzymes of the 10-23 type cleave the target mRNA to purine-pyrimidine sequence sequences.
- DNAzymes are known as well as their use for the specific inhibition of the expression of GATA-3 or Tbet.
- WO 2005/033314 A2 describes the mode of action of various DNAzymes.
- the disclosure of WO 2005/033314 is considered to be the technological background of the present invention.
- nucleic acids tend to rapidly degrade, for example, by enzymatic degradation or physical stress - this is especially true for single-stranded nucleic acids, which include DNAzyme.
- an active substance for therapeutic purposes is followed by the question of the applicability of the active substance.
- a locally targeted application is needed, you want to fight the inflammatory focus efficiently or reach the target cells targeted.
- an active agent is most effective if it can be ingested via the lungs.
- Inhalation allows patients to take agents into the lungs or through the target cells in the lungs, allowing the agent to be site-specific or to be rapidly absorbed into the bloodstream via the alveoli. This method can reduce the risks of side effects in the rest of the body. In addition, a lower dose is necessary because a much larger dose proportion reaches the site of action than by non-specific application.
- Inflammatory diseases are limited mainly to drugs that have a strong immunosuppressive effect. Examples of such agents are
- Corticosteroids mesalazine (5-aminosalicylic acid), ciclosporin, tacrolimus or TNHa antibodies. None of the above-mentioned therapeutic options is suitable for targeted use. Rather, the substances used for their strong immunosuppressive effect are known. In addition, the substances are associated with common side effects such as immunosuppression, hepatotoxicity, myocardial hypertrophic gastrointestinal disorders, fatigue and dizziness, diarrhea, vomiting, nephrotoxicity, neurotoxicity, tremor, hypertension, insomnia, depression, convulsions, masking of infections , Hyperkalemia, hyperglycemia, increased risk of tumors - just to name a few.
- the invention is therefore based on the object of providing a DNAzyme-containing composition for the treatment of a patient suffering from a chronic inflammatory disease associated with respiratory disease, which is suitable for targeted application.
- the composition should be able to be absorbed via the lungs of the patient to be treated, which is why it should be easy to nebulize.
- the drug should minimize the risk of side effects.
- compositions for the treatment of a patient suffering from a respiratory disease associated with chronic inflammation comprising at least one DNAzyme which specifically down-regulates the expression of GATA-3 and / or comprises at least one DNAzyme containing the Expression of Tbet downregulated specifically.
- the composition is characterized in that the DNAzyme is present in the composition in a concentration which is lower than 75 mg / ml.
- the composition can be applied as an aerosol, which is absorbed via the lungs.
- the composition may be a liquid or a solution, alternatively a powder. It is known to the person skilled in the art that a downregulation of an expression can be understood to mean both partial and complete inhibition of the expression.
- expression is significantly reduced compared to the natural level of expression.
- the specific DNAzymes bind and cleave in vivo the mRNA of the transcription factors GATA-3 and / or Tbet, whose proteins represent key key molecules for the development of Th1- or Th2-dependent chronic inflammatory diseases. Due to this cleavage of the mRNA, the mRNAs can no longer be translated into functional proteins. Consequently, the level of GATA-3 and Tbet protein is significantly minimized.
- composition of the invention having a DNAzyme concentration lower than 75 mg / ml, is ideally suited for the treatment of patients suffering from respiratory disease associated with chronic inflammation. This is mainly because compositions with DNAzyme concentrations exceeding 75 mg / ml are associated with drug loss. The reason for this is that such highly concentrated compositions can no longer readily be atomized due to their increased viscosity (for example via an inhalation device). Hand inhalers customary in medicine generally work with an atomization pressure of 40 bar to 45 bar. For such an inhaler, the surface tension of a solution having a DNAzyme concentration of over 75 mg / ml is too high to be still atomizable.
- compositions with a DNAzyme concentration of 75 mg / ml show a drug loss of about 6% when administered by means of an inhaler.
- compositions with a DNAzyme concentration of 20 mg / ml to 50 mg / ml have an optimal effect effect when treated with an inhaler, because compositions with such concentrations can easily be sprayed.
- a composition is preferred according to the invention, which has a DNAzyme concentration of 20 mg / ml to 50 mg / ml.
- the composition according to the invention can be present in particular as an inhalation solution which can be administered as an aerosol into the lungs of a patient, which is of particular advantage in the treatment of respiratory diseases, which are triggered by allergic inflammatory reactions.
- the active ingredients DNAzymes
- the composition according to the invention in aerosol form Place the inflammation to be applied.
- the composition is a liquid or a solution.
- the composition may be a powder.
- the feature according to the invention is of great advantage in particular when using DNAzymes.
- concentrations are usually possible which far exceed 75 mg / ml, without significantly increasing the viscosity of the solution.
- smaller DNA molecules ⁇ 1,000 bp
- DNAzyme can be present in concentrations of more than 100 mg / ml, without the solutions becoming particularly viscous.
- DNAzymes In DNAzymes, however, the surprising effect that DNAzyme-containing solutions become disproportionately viscous even at concentrations of at least 75 mg / ml. At concentrations above 75 mg / ml, they even fail. The reason for this is above all the three-dimensional structure of the DNAzyme, which is characterized by the formation of a "loops" or a "loop". Due to this particular structure, DNAzymes, promoted by their single-strandedness, can form a kind of polymer structure and easily clump together, which in turn results in an overall poor solubility of high amounts of DNAzyme.
- the composition according to the invention is of great advantage because it is not too viscous due to a DNAzyme concentration of less than 75 mg / ml and therefore easily administered as an aerosol leaves.
- the composition has a DNAzyme concentration of 20 mg / ml to 50 mg / ml.
- a DNAzyme concentration of 20 mg / ml to 50 mg / ml ensures that even when using handheld inhalers or similar inhalers sufficient amounts of active ingredient can be absorbed by the patient.
- DNAzyme concentrations below 20 mg / ml there is a risk that the quantities of active substance delivered by a single triggering or actuation of an inhaler will not be sufficient to achieve the desired treatment result - it will be simple per triggering of the inhaler too few active ingredients delivered. Consequently, patients must operate the inhaler several times, which on the one hand represents a possible burden for the patients to be treated and on the other hand ensures a higher wear of the inhalers. Due to a high concentration of active ingredients several applications per inhaler are possible.
- composition according to the invention thus ensures an ideal compromise, especially in this preferred embodiment: on the one hand, the DNAzyme concentration of less than 50 mg / ml is still low enough to be atomized by an inhalation device, on the other hand the DNAzyme concentration is more as high as 20 mg / ml sufficiently high that, for example, when using handheld inhalers sufficient drug levels can be delivered after a few operations.
- the composition has a viscosity which is lower than 3.5 mPa ⁇ s.
- a viscosity has the consequence that the composition can be applied without problems and without significant loss of active ingredient as an aerosol, for example as inhalation solution of an inhaler.
- a higher viscosity has the consequence that the pressure which must be used to atomize the composition is too high to be exerted by a conventional inhaler.
- a composition with a viscosity of over 3.5 mPa.s may cause the nebulizers of the inhalers, which are usually used to treat corresponding patients, clogging or smearing after a short time. It is therefore advantageous that the viscosity of the composition is in a range which ensures the highest possible concentration of active ingredient (DNAzyme) at relatively low viscosity.
- DNAzymes of the earlier application DE 103 46 487 are mentioned as DNAzymes and included in this application. These DNAzymes are directed against the mRNA of GATA-3 and T-bet proteins and disclosed for the production of an anti-inflammatory agent.
- DNAzymes are used (each alone or in combination with the others): Name of the DNAzyme against GATA-3 mRNA sequence:
- the DNAzyme is selected from a group comprising the DNAzyme hgd1 to hgd70 (cf., also Table 2) and / or from a group comprising the DNAzyme td1 to td78 (see Table 2).
- DNAzymes with either of these sequences are found to be particularly efficient for specific in vivo inhibition of the expression of the pro-inflammatory transcription factors GATA-3 and Tbet, respectively.
- the sequences are preferred, the substrate binding domains are fully complementary to the flanking regions of the cleavage site of a particular target mRNA.
- a DNAzyme need not be fully complementary to bind and cleave a target mRNA - smaller complementary sequences may be required within the overall homologous substrate binding domain.
- composition which has the DNAzyme hgd40 GTGGATGGAggctagctacaacgaGTCTTGGAG (SEQ ID No. 40) for downregulation of the expression of the transcription factor GATA-3.
- This sequence shows a particularly high enzyme activity and cleaves GATA-3 mRNA with a high specificity and with high efficiency. Consequently, a DNAzyme with the sequence hgd40 (SEQ ID No. 40) is excellently suitable for the targeted and effective treatment of respiratory diseases which are Th2-dependent, that is to say corresponding to an elevated GATA-3 level.
- the composition may have at least one nuclease inhibitor, wherein the at least one nuclease inhibitor in particular specifically inactivates deoxyribonucleases, ie a DNase inhibitor.
- the at least one DNAzyme is protected from enzymatic degradation which can be caused by DNases.
- composition comprises at least one salt and / or at least one cation.
- Such a composition is advantageously suitable for use in the therapy of patients suffering from a respiratory disease associated with chronic inflammation, because the composition thereby has a physiologically favorable environment and is thus easily tolerated by patients.
- a phosphate buffered saline solution PBS
- the inorganic and / or organic additive is preferably selected from the group comprising the substances sodium chloride (NaCl), potassium chloride (KCl), disodium hydrogen phosphate (Na 2 HPO 4 ), disodium hydrogen phosphate dihydrate, potassium dihydrogen phosphate (KH 2 PO 4 ), TRIS and EDTA.
- the cation may be selected from the group consisting of Na, Mg, K, Li, Ca, Fe, Cu and Ag.
- an organic cation may be provided, such as Mg (N (S0 2 CF 3) 2) 2 or Mg (0S0 2 CF 3). 2
- a bivalent cation can be provided.
- Such a buffered composition is particularly suitable for the protection of the DNAzyme, because the DNAzyme is stabilized by the inorganic and / or organic additive and protected from enzymatic degradation.
- the salt allows a good uptake into the target cells.
- the bivalent cations as cofactors of DNAzymes, can increase DNAzyme activity since the DNAzymes have a catalytic domain dependent on bivalent cations (preferably Mg 2+). Thus, bivalent cations act as enhancers or enhancers.
- the composition may comprise at least one inorganic and / or organic additive and / or a solubilizer and / or a preservative.
- the solubilizer mainly serves to form the complex. In addition, it improves the solvent properties of the composition.
- the solubilizers may preferably be glycerol derivatives and / or polyethylene glycols or else lecithins.
- the preservative may be, for example, paraben.
- additives may be provided which cause, for example, a change in the surface tension of the composition or a decrease in the viscosity of the composition.
- An additional aspect of this invention is the process for preparing the composition according to the invention, wherein it is provided that the process comprises at least the following steps:
- step b) filtering the solution from step a) until the solution has a DNAzyme concentration of less than 75 mg / ml;
- the filtration step is advantageous because it removes unwanted (non-sterile) substances as well as undissolved active substance particles (ie undissolved DNAzymes).
- the composition must be sterile for the treatment of a patient suffering from a chronic inflammatory respiratory disease.
- Other sterilization methods radiation, heating, autoclaving, etc.
- the solution is sterilized by filtration.
- a filter is preferably used, the PES membrane having a pore diameter of 0.20 to 0.25 pm. Particularly preferred is a PES membrane, with a pore diameter of 0.22 pm.
- the method comprises at least one further method step, namely selected from one of the following steps:
- Such a method conveniently provides for the preparation of a composition that can be used to treat a patient suffering from a respiratory disease associated with chronic inflammation. By selecting the steps, the process can be individually adapted to specific needs.
- a further aspect of the invention is the use of the above-mentioned composition as a medicament for the treatment of a patient suffering from a respiratory disease associated with chronic inflammatory diseases.
- the composition can be present in particular as an inhalation solution.
- other forms are also conceivable, such as a powder for use in powder inhalers.
- the composition can be applied in the form of an aerosol.
- an applied composition may be site-specific in the lung of a patient suffering from a respiratory disease associated with chronic inflammatory disease. This can increase the effectiveness of the drug. At the same time, the risk of side effects is minimized.
